SPECIFICATION forming part of Letters Patent N o. 653,393, dated. Julyy10, 1900.

Application led October 20, 1899 Serial No. 734,250. (No model.)

T all whom, it may concern:

Be it known that I, ELLsWQRTH M. PAGE, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Book- Cover, of whichthe following is aspecification.

This invention relates to book-covers; and the object in view is toprovide a temporary .cover for the backs or bindings of books adapted tolit varying sizes of the same and be inseparably held when applied byusing two substantially-triangular pieces of paper or other suitablematerial so shaped and vde signed as to allow the sealing of one'cornerof each section and an arrangement thereof to slip on each back-sectionof the book and subsequently unite both sections on a'diagonal lineacross the backs or bindings of the book by adhesive material preferablycarried by said sections.

With this and other objects in view the invention consists in theconstruction and arrangement of parts, which will be more fullyhereinafter described and claimed.

In the drawings, Figure l is a perspective View of a book, showing thebacks or bindings open and the improved temporary cover applied thereto.Fig. 2 is a similar view of the improved temporary cover, showing thesections united and looking toward the interior thereof. Fig. 3 is asimilar view of the improved temporary cover looking toward the outsidethereof and also showing the sections connected. Fig. 4 is a plan Viewof one of the blanks of which each section is made up.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numerals 1 and 2 designate substantially-triangular sections, ofwhich the im;

proved temporary cover is composed. Each of these sections is made upfrom the blank shown by Fig. 4, and as both are precisely alike only onewill be particularly described. The section-blank comprises'a body 3,having an outer side edge, elongated iiap 4, adapted to be turnedinwardly on a folding-line 5 and merging into or continuous with atongue 6 in a plane substantially at right angles to the flap 4.Adjacent the tongue 6 is an interme diate tongue 7 and succeeding thisis an inner tongue 8. The tongues 6,7 ,and 8 are adapted to beturnedinwardly over the body 3 on fold ing-lines 9, the lines of the tongues 7and 8 being virtual continuations of that of the tongue 6. Between theouter tongue 6 and the adjacent edge of the intermediate tongue 7 arecess 10 is formed at the base of said tongue 7 and duplicated, as at11, at the opposite portion of the base of the same tongue, bothrecesses ex- 6o tending inside the plane of the folding-line 9, and theedges of the tongues 6 and 8 nearest the tongue 7 slope down graduallyand merge into the said recesses 10 and 11. The greater portion of thetongue 8 is regularly rounded 65 into a similar coating 16, extendingalmost completely over the inner surface of the edge of the closing-flap13.

In arranging the sections for application the side iiaps 4 are turnedinwardlyand secured by moistening the adhesive material on the 8o tongue6 and simultaneously bending in the tongues 7 and 8 and sealing tongue 7to the body 3. The one section is then ready for application over onecorner of one of the book backs or bindings, and the opposite section issimilarly prepared and, positioned reversely to the iirst sectionapplied over the remaining book back or binding. The two sections arethen united by moistening the adhesive material 15, which, it will beunderstood, is pref- 9o erably applied on one section or thatl havingits edge 12 exteriorly exposed at the back. To complete the applicationof the temporary cover, the folds 13 are inturned, preferably in oneinstance over the adjacent part of Athe flap 4, and then the twosubstantially covered by the inturned tongue S of the opposite section,and at the other corner the similarly-inturned tongue 8 is caughtbeneath the adjacent portion of the iiap 4 of the section havroo Thetongues 6, 7, and S 7o e masse ing its tongue turned in over the iiap13, and the Hap 13 at said opposite corner is bent in over the inelosedtongue 8 and a portion of the flap 4 of the same section, and thetemporary cover is firmly secured in place against accidentaldisengagement.

It will be observed that when the temporary cover is applied, as clearlyshown, the line of connection of the two sections will extend diagonallyacross the back of the book and the bindings thereof, and thereby befree from pulling or separating strain and materially superior to theform of book-covers having closing-seams running in lines parallel withthe center of the back or along opposite top and bottom edges. Afurtheradvantage of the present construction is the simplicity and rapidity ofadj ustin the section squarely andy snugly to the book backs orbindings.

The covers are made in different sizes and each size is adjustable tofit different books or those having variations in dimensions withinacertain limit. The improved device requires less stock in itsconstruction than other devices of a similar character heretoforeproduced, and at the top back edge of the book asmooth surface is alwaysprovided on the cover, on which may be written the title, number, rbc.,of the book. A further advantage is in the manner of providing theintermediate tongues and forming the recesses 10 and 11 inside of theplane of the folding-line of said tongues and then continuing the saidrecesses into the adjacent edges of the tongues 6 and 8 above thefolding-line. Then the device is applied, by this construction justreferred to, no strain comes on the edge of the cover at such pointswhen the book isopen, and the improved device is reinforced ata portionthereof where, in most covers, as heretofore made, a great weaknessexists.

Changes iu the form, proportions, and minor details may be resorted towithout in the least departing from the nature or spirit of theinvention.

Having thus described the invention, what is claimed as new is 1. Abook-cover of the character set forth, comprising in its completemake-up two du- ;plicate triangular sections which have their meetingedges joined and the joint extended diagonally across the centralconnecting portion of the back of the book to which the cover isapplied.

2. A book-cover comprising separate secv tions having diagonal edgesadapted to be joined and also provided with iiaps and tongues ondifferent sides which are reversely arranged in the opposite sections,the

diagonal joint of the said sections extending across the centralconnecting portion of the back of the book to which the cover isvapplied.

3. A book-cover of the character set forth, comprisingseparate sectionsof duplicate-contour adapted to be joined on a diagonal line across theback of the book towhich they are engagement with the hinge portion ofthe book, recesses extending inwardly on opposite sides of theintermediate tongues and having the adjacent edges of outer and innertongues gradually merging thereinto.

4. A blank for a section of a temporary book-cover having asubstantially-triangular form and provided withv an outer sideflfap,outer intermediate and inner tongues on one edge and a closing-Hap onthe opposite edge, the edge between the inner tongue and the saidclosing-flap being in a diagonal plane.

In testimony that I claimv the foregoing as my own I have heretoaiiixedmy signature in the presence of two witnesses.
